TEMPORARY BINDER.

Specification of Letters Patent.

Patented Nov. 24:, 1914.

Application filed October 7, 1912. Serial No. 724,420.

To all whom it may concern Be it known that I, CHnsLnY Don, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Temporary Binders, of which the following is a specification.

My invention relates to an improvement in loose sheet binders, preferably of a type in which a follower or movable cover member is slidable upon posts secured to a base, with the base likewise serving as a cover member. In binders of this class the follower or movable member is free to move in one direction, that which binds the loose sheets between the cover members and automatically locks against movement in an opposite direction, with a release in such opposing direction manually effected.

The object of my invention is to provide a follower or movable member of a loose sheet binder slidable upon posts and locked to the posts by a reverse action or pressure and in which the locking instrumentalities are comprised in a wedge member disposed angularly relative to the postwith which it engages to impinge against the same and frictionally lock therewith in one direction of movement, automatically releasing in areverse movement, with the wedge qualifying as a lever for controlling a positive release. Another object of my invention is to provide a series of clamping members within a casing of the follower member of the loose sheet binder, through which impaling posts are adapted to project, one for each locking member, with the locking member producing a wedge-like action between the follower member and post, to resist a reverse movement of the follower member upon the post, while free to move in a forward direction, the clamp qualifying as a lever and capable of being rocked and maintained in a released position, and a movable member slidable within the casing and accessible from the exterior, adapted to engage all of the locking members of the binder for simultaneously controlling the same to swing the same into and out of operative position.

Another object of my invention is to provide a follower member of a loose sheet binder with a notch or notches depending upon the number of impaling posts with which the follower engages, with the tion effect a notch clearance offering easy and convenient removal and insertion of the follower member upon the post or posts when a plural number of binding elements are employed.

The follower is provided with a locking member movable to and from a position of engagement with the posts, and capable of locking therewith in one direction of movement, and at the same time bridge the notch at the outer side of the post to prevent displacement of the follower and posts.

As a specific characteristic it is the object of my invention to provide a follower of a loose sheet binder with an angular notch extending from one edge thereof to provide engagement with the post at any point, with a wedge member qualifying as a lever mounted on the follower, one for each post, notched to partially envelop a respective post and partially close the notch gap and circumferentially bind the posts within the follower. The follower is provided with a slide member of integral form having elastic and non-elastic portions, engaging each of the wedges and alternately with the lever ends, to swing the same into and out of post engagement, and maintaining the same under tension during post engagement toward a binding direction.

The features of my invention are more fully set forth in the description of the accompanying drawings, forming a part of this specification, in which Figure 1 is a top plan view of the clamping end of the follower or cover member of a loose sheet binder illustrating the same in a clamped position upon a pair of impaling posts with the posts shown in section. Fig.

2 is a section on line 00, 00, Fig. 1. Fig. 3 is a detailed top plan view of the locking members mounted in position upon a base plate of the follower with the casing covering the same removed. Fig. 4 is a detailed plan view-of the sliding member, serving as a latch plate for controlling the operation of the post lampin members. Fig. is a section similar to it 2, showing the sliding latch plate of modified form.

' 1e drawing the stationary cover r or base of the loose sheet binder, carries the impaling posts is omitted, the same is of common and well-known lotion, and therefore, elaboration is ential herein, as the same is common bind of this class. in general, how it is comprised in a plate inclosed within a covering, having a cover flap hinged thereto, with a pair of impaling posts socured and projected from the plate. 1 and 9; represent PlCll impaling posts upon which the follor-ier or cover member 3 moves and is clamps l. The follower preferably coniprises a. to i: usually inclosed within a (ZlO'cJ covering, and o which a cover flap ('3 gcd, the coyering forming the hinge the oinuer in use presents a heel: aent, irrespective of the number of s amped between the cover elements, and re erence may be had thereto, without 2.5 c urbing the binder members.

.lne plate t is provided with the angular notches 7, 8 througl'i which the posts 1, 2 respectively project, the angular disposition of the notches functioning to permit a lateral removal of the follower member 3 from the posts when the locking instrumentalities are in a. released position, and also functions in preventing such lateral movement when the locltin instrumentalities are in an active position. This feature, however, will be more fully described and it is obvious that this notch feature is not ma erial to certain aspects of the invention in which lateral removal of the follower member is not a characteristic of the binder. An orifice could .xually as the angular slot or notch to receive the posts, in which instance vertical ivement of the follower men her is necested in inserting or withdrawing t ie same 45 from the posts, and therefore, 1 do not wish to be imited to a lateral removable type of iollower cover member, except in so far as this feature may be embodied in the claims. 9 represents casing secured to the upper surface of the p 4:. The casing at its ends is provided with projecting tangs adapted to pass through orifices in the plate 4 and bent parallel with the lower surface of said late, providing fastening means for securi the casing to the plate. It is also provided with the angular notches 10, ll, coinciding respectively with the notches 7 and 8 of the plate 4-.

12', 13 represent lock lever members, one for each pos provided with tangs 1% pro- Vii jecting from the intermediate portion thereof, which engage into orifices 15 formed in the plate l. lihis provides a loose socket connection, and serves as a. pivot for the lever. fine edge of each tang is straight and positions parallel with an adjacent post and when en aged with the wall of the orifice forms an abutment for one limb of the lever when functioning as a wedge. The second edge 1'? developing in an arc, offeing clearance for a free reciting or swinging movement of the lever.

it is obvious that the lock lever or wedge member can be constructed to serve only as a, wedge, other instrumentalities than those shown being provided for producing a manual release of the member from a post engagemei without departing from the general characteristics or features of my invention. The lever formation hercinillustrated defines one type designed for the specific manual releasing mechanism, enabling an elastic element to be employed productive of multiple functions havin inherent advantages.

'lhe wedge limbs of the lever or look members l2, 13 are provided with notches 19 corresponding in outline somewhat to the radius of the post, so as to produce an overlapping edge capable of protruding into the notch clearance of the follower to prevent longitudiiuil displacement of the follower when en god with the posts, and thereby prevent radial removal of the follower or movable cover member from the post when the wedge member or limb is in a locking position.

its illustrated, the wedge only partially blocks the gap of the angular notches, which is sufficient to achieve the result desired, and enables a very restricted movement of the wedge member to effect a release and clearance of the notch gap. The angular disposition of the notch directs the release of the follower member toward the wedge and t0- gether with one edge of the notch in the wedge-member produces a very substantial circiunferential incl sure of the post within the follower member. This, in service, is

substantially equivalent to a complete bridging of the notch against radial longitudinal movement or a relative angular movement of the cover or follower member, which would effect a removal thereof from the posts and with a further result that the parts have a tendency to more securely loci: togetl or against any accidental radial movement of the cover member.

To simultaneously move the pair of wedging lovers 1 provide the slide member 20 slidably mounted to the interior of the easing 8 by a button 21 having a shank 22 projected through an oblong slot J) in the easing 8, and riveted or liXed to the slide 20. This slide is preferably formed. of flexible material, in order that its free ends, which en age respectively with the lever members and 13 may function as springs for yieldingly maintaining the wedge limbs of the lever members in their post-engaging positions. The ends of the slide are preferably provided with a corrugation adapted to seat within a notch or groove 26 in the wedge limb to offer resistance against a free movement of the slide 20 toward a releasing direction, andthereby prevent accidental displacement of the parts;

As shown'in Fig.2, the end of the slide 20 is engaged with the wedge limb of the levers,

I brin in the limbs into en a ement with the D b b 23 ducing a wedge-like action between thelimb 2d of the lever and theupper wall of the casing during a releasing movement of the slide 20, forcing the levers to move or swing away from their post engagement. This insures a positive release of the locking elements, should an exceptionally tight bind result from a wedge-locking action, the end of the slide operating in such instance as a rigid non-elastic member.

As shown in Fig. 4, the slide 20 at its intermediate portion is provided with the V- rib 25 serving as a reinforcement thereof, strengthening such portion and enabling the production of the slides from flexible material as an integral element having portions rigid against flexation, while portions thereof are yielding, which is quite an advantage in its manufacture, as the whole is a stamp ing.

t will be seen that the various elements are united and mounted in position without the employment of auxiliary fastening instrumentalities, enhancingits durability and convenience of assemblance, with a minimum number of parts.
